GTA-IVaud 1.1

GTA-IVaud is an ivaud pcm audio replacement utility. It allows modders to replace audio within ivaud archives which have been extracted using other 3rd party utilities from rpf archives. Currently it does not support the showing of filenames however, since the filenames for audio files are not stored in the ivaud archives themselves.

This program will allow modders to export, and reimport audio files of any length into existing ivaud archives. I replaced the M4 fire sound myself and it worked nicely in game!

By all means! Thank you! Link me to it! lol.. You might mention in your thread that the current version 1.1 will open many IVAUD files, but cannot open IVAUD files containing radio station or speech data. Version 1.2 of my program (which I am working on now) will be able to open all ivaud file-types however.

Just an update for those interested, I am currently working on version 1.2 and it will be able to display the filenames, as well as edit IVAUD files with radio station audio and speech audio! I'll upload it to this site as soon as i've completed it.

At my computer is doesnt work good. I am trying to add a dutch siren but when i use it in game, i hear it good for about 3 seconds and then i hear a sound that looks like u hear when your tv is on a not working channel for about 3 seconds. Then the normal sound is starting again and so be.
Does anyone know a solution for this problem? I tried another sound and that didnt workd either.

I'm still not sure about little endian. Even you have 16bit 26000khz mono pcm uncompressed file, it can still come out big endian as somebody explains on internet. If thats so, then which software can correct it? I checked BeSweet, River Past Audio and I'm using Steinberg Wavelab for few years and i can't find such option for uncompressed pcm anywhere. When i replace audio file with correct length and all other parameters i get NO error replacement message, but file gets downsized from whatever it is to 4kb. After i save it and exported again, to check it in wavelab, it shows as mono 16bit 26000khz SILENCE, lol. So maybe one day we'll get it right.

Goldwave allows you to specify between little and big endian when saving files. Depending on the ivaud you are editing, my program may be incorrectly placing it in the ivaud file. I'm working on 1.2 right now and redesigning the ivaud IO system from scratch to resolve the issues i've discovered along with the modding community over the past week. I already have it showing filenames! :D

Thank you for response, I'll check it up. And of course we all appreciate your effort to create this. I did change one weapon sound, but it had to stay original. I used sound from something else to make grenade launcher mod sound like poping grenade, instead of shotgun sound. That way i kept rocket launcher.

I am having issues implementing the IMA/DVI Adpcm decoder and encoder. As a result, I plan on releasing 1.1.5 soon which resolves some bugs and adds support for showing filenames, but still does not support replacing radio station or speech audio just yet. 1.2 will be out well before the end of the month, it would be out sooner but my college courses start up again next week. =)
